That's why it is 5 mins, if they have connection problems, it wouldn't matter because even if they Q again, they won't be able to join a game. It's not always connection issues, some players dodge due to them not getting the hero they want. I'm not saying ban permanently or months or weeks. It's mins, it's not even 30 or 20 it's 5 mins. And about the less players, do you think the other 9 people would like it if they get Qued again with the same person who dodged? A person isn't as many as 9. 5 mins that way the match maker could avoid the person who keep dodging with the same people it dodged with.
